[0002] Air-to-water equipment produces water based on physical properties and uses a single refrigeration technology to achieve the purpose of condensing water. Most of the existing air-to-water equipment uses fixed-frequency technology. Fixed-frequency devices have only two states: working and not working. There is no effective energy-saving method.

[0028] Working principle of this utility model:

[0030] Principle of off-grid solar energy storage water production system 1: The main control board located on the back of the main control cabinet has multiple signal input and output interfaces. All technical operation logics of the air water production equipment are controlled by the main control board. The main control board analyzes the temperature and humidity and sets the internal program according to the temperature and humidity monitoring of the external environment temperature and humidity sensor 121 and the internal temperature and humidity sensor 122, adjusts the working state of the frequency conversion device, forms an effective temperature difference between the circulating air and the surface of the evaporator 12, and realizes condensation water production;

[0031] The main control board automatically calculates the optimal operating power of the variable frequency compressor 14, the variable frequency air circulation fan 132, and the electronic expansion valve 16 based on the temperature and humidity difference collected by the external environment temperature and humidity sensor 121 and the internal temperature and humidity sensor 122, combined with the temperature difference ratio required for the maximum water production volume set in the main control board, and outputs the corresponding drive signal to control the variable frequency compressor 14, the variable frequency air circulation fan 132, and the electronic expansion valve 16 to operate in variable frequency, so as to achieve the optimal water production effect and operate in the most energy-saving working condition;

[0032] As shown in the figure, when the air-to-water equipment is in operation, the high-temperature and high-pressure gaseous refrigerant output by the variable frequency compressor 14 passes through the high-pressure copper tube 142 and the four-way valve 15, and then enters the condenser 13. The condenser 13 completes the heat exchange of the refrigeration system, and dissipates the heat generated by the refrigerant in the compression process of the variable frequency compressor 14 to the external environment. The high-temperature and high-pressure gaseous refrigerant is converted into medium-temperature and high-pressure liquid refrigerant after passing through the condenser 13. The electronic expansion valve 16 controls the refrigerant circulation rate according to the driving instructions of the main control board, and converts the high-pressure liquid refrigerant transported from the copper tube into a low-pressure liquid refrigerant. The electronic expansion valve 16 controls the refrigerant The circulation rate causes the high-pressure liquid refrigerant to be depressurized due to throttling, ensuring that the refrigerant has a suitable pressure after passing through the electronic expansion valve 16. At the same time, the electronic expansion valve 16 controls the speed at which the refrigerant enters the evaporator 12. After the low-pressure liquid refrigerant enters the evaporator 12, the internal channel of the evaporator 12 suddenly expands, the refrigerant pressure is reduced, and it evaporates and gasifies rapidly, absorbing a large amount of heat, causing the surface temperature of the evaporator 12 to drop sharply, causing a large temperature difference between the evaporator 12 and the external environment, thereby causing the moisture in the circulating air to condense on the surface of the evaporator 12, and the condensed water droplets are collected by the water collection tray 131 to achieve effective water production;
